3 Water-To-Water Design Features Carrier Geothermal Heat Pump Systems The series is unlike any other water-to-water heat pump on the market today. The large operating map of the scroll compressor allows high temperature operation, up to 145 F [63 C] leaving load water temperature even at 32 F [0 C] entering source water temperature. The combination of a coaxial (tube-in-tube) heat exchanger for the source (ground loop) side and a brazed plate heat exchanger for the load (heating/hot water) side provides very high effi ciencies. Integral controls for hydronic heating and domestic water heating avoid the need for external microprocessor-based controls for outdoor temperature reset, warm weather shutdown, staging and other controls. The has an extended range refrigeration circuit, capable of ground loop (geothermal) applications as well as open loop (well water) applications. Standard features and factory-installed options are many. Unique application-specifi c controls make the series ideal for hydronic heating and domestic hot water generation. The heating-only refrigeration circuit is optimized for high water temperatures, heating effi ciencies, and capacities. The dual level compressor isolation mounting system, insulated compressor enclosure, and compressor discharge muffl er make the series one of the quietest water-to-water heat pumps available. The attractive Euro-style cabinet allows the unit to fi t into any decor. Application Flexibility Capacities 10kW [32,600 Btuh]. High temperature scroll compressor, up to 145 F [63 C] leaving water temperature. Ultra high effi ciencies (4.2 COP at ground loop conditions; up to 5.5 COP at ground water conditions).
